Answer: B)
Step-by-step explanation:
If y = z then replace z for y in the second equation.
2 y + z = 12
2y + y = 12
3y = 12
y = 4
This also means z = 4.
Insert both of these values into the first equation:
x + y + z = 8 + 2sqr3
x + 4 + 4 = 8 + 2sqr3
x + 8 = 8 + 2sqr3
x = 2sqr3

Answer:
1. 195=6.50·c
2. 30
Step-by-step explanation:
195=6.5·c
Divide both sides by 6.5
30=c
L = Length
W = Width
L x W = area
Length = 2w
Lets find the width by solving for w.
2w + w = 36
3w = 36
3w/3 = 36 / 3
w = 12
So
L = 2 x 12 = 24
W = 12
L X W = area
24 x 12 = 288 cm^2
